[x] tabs

What is the current behavior?

You have to add brn and hlm directives to all the tabs components.

Closes #

What is the new behavior?

As we decided to make the hlm dependand on brn, we can simplify the api.

tabs

old: <brn-tabs value="account"> new: <div brnTabs="account">

tabs-list

old: <brn-tabs-list hlm> new: <hlm-tabs-list>

tabs-trigger

The brn is a hostdirective of the hlm and does not need to be provided. old: <button hlmTabsTrigger brnTabsTrigger="account"> new: <button hlmTabsTrigger="account">

tabs-content

Same as trigger. old: <div hlmTabsContent brnTabsContent="password"> new: <div hlmTabsContent="password">

Does this PR introduce a breaking change?

[x] Yes
[ ] No

You will get the following error for tabs-list, trigger and content: Directive BrnTabsTriggerDirective matches multiple times on the same element. Directives can only match an element once.

In this case, brnTabsTrigger should be removed. See "new behavior part" of this PR.

Other information

We also added tests for brn-only to make sure @Input of brn also still works correctly.
